Star apple (Chrysophyllum cainito), a tropical fruit from the Sapotaceae family, is valued for its fruit, ornamental appeal, and medicinal potential. This study evaluated nine genotypes from Kerala, showing variability in tree height, yield, and shelf life. Tree height ranged from 2.54 m to 9.36 m, with larger trees like Collection 09 yielding more. Shelf life ranged from 3 to 6 days, with Collection 08 having the longest shelf life. PCA and correlation analysis showed tree height and age were positively correlation with yield. High-yielding genotypes like Collection 09 and those with superior shelf life, like Collection 08, are promising for breeding and commercial use.
